Abstract

The present invention relates to an LED photocatalyst module comprising: a light supplying section for radiating light to a photocatalyst so that the photocatalyst is activated; a photocatalyst purifying section which is formed separately from the top of the light supplying section, for purifying polluted air; and a discharging section which is formed separately from the top of the photocatalyst purifying section, for sucking in the air purified by the photocatalyst purifying section and discharging the air to the outside, wherein the photocatalyst purifying section comprises a ceramic honeycomb structure in which a number of photocatalyst stomata, coated with the photocatalyst, are combined in a honeycomb form, and wherein the photocatalyst comprises a porous metal oxide film; and metal particles formed on the surface of the porous metal oxide film.

Description

Utilize the Light-Emitting Diode photocatalyst module of catalysis material
Technical field
The present invention relates to the Light-Emitting Diode photocatalyst module utilizing catalysis material.
Background technology
Along with the development of modern society, atmospheric pollution is more and more serious, and along with the increase of time resting on the interior space, the demand for the improvement of the air quality of indoor also increases gradually.Further, in recent years, along with the appearance of the high virus of infectiousness, the danger of disease is together increased, and, due to humidifier antibacterial the reason such as toxicity focus and need harmless antibacterial, sterilised products.
In this, the air purifying process of photocatalyst is utilized to get most of the attention, and the product of variform also just conventionalization.But, when the universal product of powder or coating liquid form, there is position because being suitable for different and there is the problem of larger performance difference, and, be provided with the product of the air purifier of photocatalyst and light source and so on as single product, there is the shortcoming that cannot realize multiple use.
Therefore, can also present high activity under visible light Light-Emitting Diode to utilization, and can realize removal harmful substance, the requirement of user of small-sized Light-Emitting Diode photocatalyst module of catalysis material of deodorization and antibacterial functions still continuing.

Below, embodiments of the invention are described in detail.These examples propose as just illustration, and the present invention is not limited thereto, and the present invention only defines according to the claimed scope of invention.
In an example of the present invention, Light-Emitting Diode photocatalyst module is provided, comprise: light supply unit, for irradiating light to photocatalyst, make photocatalyst activity, photocatalyst purification portion, the top of above-mentioned smooth supply unit is formed in the mode separated, for purifying polluted air, and discharge portion, the top of above-mentioned photocatalyst purification portion is formed in the mode separated, and for being aspirated through the air that above-mentioned photocatalyst purification portion purifies, and externally discharge, above-mentioned photocatalyst purification portion comprises the ceramic honeycomb structural body applied by above-mentioned catalysis material, multiple photocatalyst pore is with the above-mentioned ceramic honeycomb structural body of honeycombed state combination, above-mentioned catalysis material comprises porous metal oxidation film and is formed at the metallic on surface of above-mentioned porous metal oxidation film.
At usual the used TiO of use 2when the air purifier product of photocatalyst, owing to there is the restriction needing to use ultraviolet as light source, thus have and manyly make ultraviolet restriction of exposing minimized system design aspect, and have to generate because of ultraviolet ozone etc. problem.Further, when use the product of visible light catalyst of reflection is occurred to fluorescent lamp, due in order to be suitable for fluorescent lamp carry out miniaturization in there is boundary, thus have and be difficult to realize many-sided problem be suitable for.
On the contrary, above-mentioned Light-Emitting Diode photocatalyst module can be used in Light-Emitting Diode (Lighting-EmittingDiode, LED) also present the visible light catalyst of high activity under condition, thus removal harmful substance, deodorant and antibacterial functions can be played.
Particularly, the ceramic honeycomb structural body that can comprise by porous metal oxidation film and the above-mentioned photocatalyst purification portion of catalyst coated of metallic comprising the surface being formed at above-mentioned porous metal oxidation film, such as, can use WO 3and comprise and be formed at WO 3the catalysis material (Pt/WO of Pt on surface 3) apply.The above-mentioned ceramic honeycomb structural body applied by above-mentioned catalysis material, under visible light Light-Emitting Diode, can guarantee the removal capacity of outstanding harmful substance.
